Otani ware (Otani-yaki) is type of Japanese pottery most famously known for its large size. Otani is made in the part of Naruto, Tokushima known as Otani.
The potter's wheel used in the production of Otani pottery is known as a 'ne-rokuro,' literally a 'lying potter's wheel.' One person must lie on his or her side and turn the wheel with his or her feet. The potter and the assistant must have perfect timing in order to create a successful product. Otani pottery is the only pottery in Japan that still uses this technique.
The large containers were used to hold indigo dye (Ai-game), a specialty of the region. There are also many small bowls, tea ceremony tools, vases, cups, plates, and other forms of pottery made at Otani.
In 2003, Ōtani pottery was designated as a national traditional handicraft.
